    My phone carrier and etc: AT&T, firmware: 4.3 MK2, Model: I377

    Hello community so i tried to install custom clockword recovery on my Galaxy S4 and when I booted it up I got a message with a yellow triangle that said "Firmware not authorized by AT&T" and i tried to restore back to 4.2.2 via Odin but i kept getting an error message due to the lower firmware, I tried doing an emergency firmware recover on kies and that didnt work either :( does anyone have any suggestions ive been trying to fix this for nearly 5 hours and no luck whatsoever
